Hi,

i'm at a point where i need to wait 5 seconds befor contineuing,

[PlausiblyDamp]

System.Threading.Thread.Sleep(5000)

[jorge]

System.Threading.Thread.Sleep(5000)

thanx, i'll try that

the question is. . . why do you need to wait 5 seconds?

are you waiting for some process to finish???

 

having a process wait a specific period of time to continue is poor practice. it leads to platform dependencies.

 

I am guessing you are looking to perform asynchonous processing. . .

 

look into Asynchronous Programming Overview in the help file!!!

It will make you a better programmer!

I can't see how. Perhaps you can elaborate for the benefit of those who do not know (like me). Thanks.

If you're waiting for something slower than your program, which is normally harware related, use Application.DoEvents().

 

It stops the program, makes sure everything is caught up, then continues. I remember having to use this when I was doing a LOT of reading/writing in collections from/to files (scanning 5,000 text documents for specific text, then grabbing the next word).

 

You also need to do this when displaying your graphics in a game loop. If it gets too complex.

I think the question is (again):

Why do you want to wait 5 seconds?

 

A solution can't be offered if we don't know the problem.

 

If you just want to wait 5 seconds to see who, then Sleep will work perfectly. If you're working around some issue, we'll need to know what it is to help.

i have a program i run, and i read the output, it stays open if i don't close it with: Apache_Proc.CloseMainWindow()

but if i do it to soon, i cant read the output.

Private Sub ap_test()
       With Args
           .FileName = sApache_dir & "\bin\apache.exe"
           .Arguments = "-t -n """ & sApache_service & """ "
           .UseShellExecute = False
           .RedirectStandardError = True
           .RedirectStandardOutput = True
           .WindowStyle = ProcessWindowStyle.Hidden
       End With
       Apache_Proc = Process.Start(Args)
       System.Threading.Thread.Sleep(5000)
       Try
           Apache_Proc.CloseMainWindow()
       Catch ex As Exception
           'do nothing
       End Try
       Dim sData As String = Apache_Proc.StandardError.ReadLine
       If sData = "Syntax OK" Then
           txtStatus.Text = txtStatus.Text & vbCrLf & "[" & GetTime() & "] " & "Apache Test result: Syntax OK"
           If Me.Visible = False Then
               SysTray.ShowBalloon(NotifyIcon2.NotifyIcon2.EBalloonIcon.Info, "Apache Test result: Syntax OK", "ApacheMon", 5)
           End If
       Else
           txtStatus.Text = txtStatus.Text & vbCrLf & "[" & Date.Now.Hour & ":" & Date.Now.Minute & ":" & Date.Now.Second & "] " & "Apache Test result: Error found, please check your config"
           If Me.Visible = False Then
               SysTray.ShowBalloon(NotifyIcon2.NotifyIcon2.EBalloonIcon.Info, "Apache Test result: Error found, please check your config", "ApacheMon", 5)
           End If
       End If
   End Sub

this is what i have now, and yes on a slow computer 5 sec maybe to litle, but i see no other way(if you do, feel free to comment)

[Joe Mamma]

Apache_Proc = Process.Start(Args)
System.Threading.Thread.Sleep(5000)

wouldnt this work?

 

Apache_Proc = Process.Start(Args)
while not Apache_Proc.HasExited do
Application.DoEvents()

JABE. . are you paying attention? Perhaps Platform Dependency is the wrong term as opposed to Hardware Dependency. . .

[jorge]

Apache_Proc = Process.Start(Args)
while not Apache_Proc.HasExited do
Application.DoEvents()

No, sins it doesnt close by itself

[Arch4ngel]

No' date=' sins it doesnt close by itself[/quote']

Apache_Proc = Process.Start(Args)

while not Apache_Proc.HasExited do

Application.DoEvents()

 

Here is how I see it.

 

Start a thread and in the thread...

 

while not Apache_Proc.HasExited or something like this... (while your output is not ready) Application.DoEvents

 

And outside the While... do the action needed for your outpout.

I stumble ont the awnser by acident

when i do:

Apache_Proc.Refresh() after i start the procces it exit's normaly.

so i don't need tp wait
